If you're played games like Doodle Jump and Bird Strike then Jumping Dog will be immediately familiar. You want to go higher and higher by jumping on balloons, bones (presumably, bones give the dog a burst of energy that feeds his levitation skills) and springs. You don't technically jump, but simply guide the dog with your mouse to the next object so that he doesn't plummet to the ground. The game continues as long as you're in the air. Frustratingly, the mouse controls aren't exactly precise, and can feel a little sticky depending on how taxed your computer's resources are.
